Hello,
I am working on creating custom indexer in magento 2. I have successfully created custom indexer but i want to change status "Require Reindex" of my custom indexer on following event types
1.Save - when entity is saved,
2.Delete - when entity is deleted,
3.Mass Update - when a batch of entities was updated,
when above events has run at that time i want to change the custom indexer status,
Please let me know how it is possible into magento 2? in magento 1 it is possible using _registerEvent().
Thanks
